GEORGE CHARLES CHADWIOK, OIE MELBOURNE, VICTORIA, AUSTRALIA;

APPARATUS FOR UNLOADING VESSELS.

To all whom it may concern Be it known that I, Gnonon CHARLESOI-IADWICK, a subject of the King of Great Britain, residing at .flfi:Collins street, Melbourne, in the State of Victoria, Australia, haveinvented certain new and useful Improvements in Apparatus for UnloadingVessels; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an apparatus for unloading coal or othersimilar materials from barges or other vessels, and the con' structionof the apparatus is such that it may be operated without manuallyhandling the materials. The apparatus furthermore is so constructed thatwhen not in use, the portions overhanging the wharf may be readilystowed to occupy little space so that there will be no projecting partsto interfere with vessels coming close to the wharf.

In the drawing, Figure 1 is a side elevation of my improved elevatorapparatus. Fig. 2 is a rear elevation of my improved elevator apparatus.Fig. 3 is a diagrammatic plan view of my improved elevator apparatus.Fig. 4 is a diagrammatic elevation of the tower, boom and elevator,showing the boom and elevator in their uppermost position. Fig. 5 is adiagrammatic elevation of the lower portion of the apparatus showing theelevator extending into a barge or other vessel, and Fig. 6 is adiagrammatic rear elevation of the entire apparat-us.

In these drawings, the parts comprise a staunch tower or uprightframework A constructed of stanchions or columns A suitably braced andin which are suspended a boom B carrying an elevator C and conveyers orchutes C for receiving material from the elevator C and carrying it todischarge chutes whence it may go wherever directed. At the top of thetower there are mounted a number of pulleys E. The whole tower is builton a base which is mounted on wheels F and can be moved as requiredalongrails F arranged on the wharf F by means of an electric motor G.

The boom B is constructed mainly of two staunch girders and is suspendedby ropes or chains H passing over certain of the pulleys E at the top ofthe framework A. Preferably four ropes H are employed for Specificationof Letters Patent.

this purpose, two being secured to the front portion and two to the rearof the boom B. These ropes after passing over the pulleys are connectedat their other ends to drums orwindlasses H operated by any suitablemeans. Then in its working position, one end of the boom B projects fromthe front of the framework A, and the other end, within the framework A,is preferably rounded 01f, or provided with rollers 17 which move insuitable guides 17 provided on the columns for this purpose, andcounterweights H may be employed with the ropes H to lessen the powerrequired to operate the boom.

The elevator C is constructed with its lower portion C at an angle (seeFig. 5) or hinged to the upright portion thereof, so that the former maybe moved to different angles by any suitable means.

The elevator G is suspended vertically from a turntable J mounted onwheels J running on rails J secured on the boom B. The turntable Jconsists of two parts, the upper part J carrying the elevator, havingwheels J turning on a circular track J on the lower part, the lower partbeing that which is mounted on the wheels J The turntable J ispreferably operated by an electric motor mounted on the same, anddesignated by reference numeral 14.

The co-nveyer frames or chutes C are pivoted at one end at the rear ofthe main framework A, and their other ends project from the front of theframe. They are sufliciently long to be placed in a position to receivematerials from the elevator C and there is one of these chutes at eitherside of the boom B. They may be moved in a vertical plane by ropes 10,each secured at one of its ends to one of the chutes and passing overpulleys 11 at the top of the framework A, and at their other endsconnected to suitably operated drums orwindlasses.

The elevator C consists of an endless chain 12, carrying buckets 13,which are operated within the elevator frame work by any suitablemechanism.

In the operation of the apparatus for unloading coal, the boom B islowered to lower the elevator C through the hatch of a vessel or barge Kto be emptied (see Fig. 5) and the buckets dig into the coal and raiseit, the offset or pivoted portion C of the elevator C enabling the partsof the vessel to be reached which could not be reached by a straightelevator. The elevator C has a discharge opening or openings near itstop and delivers the material to a director-plate 15 surrounding theelevator, which when the apparatus is in operation, receives the material in whatever position the discharge opening or openings 16 happento be, and directs the same to one or both of the conveyers or chutes C.The conveyors or chutes C carry the coal and deliver it to other chutesand bins or to such other conveyers as may be required.

Ascoal or other material is removed from the vessel, the boom 13 islowered by the operation of the apparatus operating the ropes ll-Lsuspending the same, and in this manner the elevator C may be furtherlowered into the hold K, and at the same time the chutes C may becorrespondingly lowered.

The boom B, as illustrated in Fig. 4:, is similar in all respects tothat shown in Fig. 1, with the exception of being provided with arecessed portion which enables the tracks J to register with the tracksM.

Near the top of the framework A two girders L are fixed, on which railsM are arranged to the same gage as those on the boom B. The boom is. cutaway at its rear portion and its line of rails is of such a length thatwhen the boom is brought to its highest position by the ropes H, therails J on1 the boom will come into line with those indicated by M fixedon the main framework A. The turntable J carrying the elevator C maybenow run onto these rails, thus transferring the weight of the elevatorG from the boom B to the framework A. The elevator C is thus broughtwithin the tower when the apparatus is not in use, and the front of theboom B is then lowered by the respective ropes 1'1. The outer ends ofthe conveyers or chutes C may be also raised by their ropes, so as tobring them practically within the framework A, thus guarding againstexcess pressure of wind and storm, by reducing the strain on theframework of the heavy projecting parts such as the boom B, elevator Cand conveyers or chutes G to a minimum, and also preventing such partsfrom forming obstructions to shipping or other operations.

I claim as my invention:

1. An elevator apparatus for coal and similar materials, comprising atower, a boom vertically movable in said tower, a

conveyer horizontally movable on said boom and a chute also movable insaid tower and pivotally connected at one end so as to be placed andsupported in an inclined position "for conveying away the materialraised by the elevator.

2. An elevator apparatus for coal and similar materials comprising atower, a

boom, means for supporting and vertically moving the said boom in thetower, a conveyer horizontally movable on said boom and a chutepivotally mounted at one one and movable in said tower, so as to bearranged in conjunction with the conveyor for carrying away the materialraised by the conveyer.

3. An elevator apparatus for coal and similar materials, comprising atower, a boom, means for supporting and vertically moving the said boomin the tower, a conveyer horizontally movable on said boom, chutes, andmeans for moving the said chutes to properly place the same in positionto carry away the materials raised by the elevator.

4. An elevator apparatus for coal and similar materials comprising atower, a boom, means for supporting and vertically moving the said boomin the tower, a turntable mounted on the said boom so as to behorizontally movable thereon, a conveyer secured to the said turntable,chutes, and.

means for moving the said chutes to properly place the same in positionto carry away the materials raised by the elevator.

5. An; elevator apparatus for coal and similar materials comprising atower, a boom, means. for; supporting and vertically moving the saidboom in the tower, a turntable mounted on the said boom so as to behorizontally movable thereon, a conveyor secured to the said turntable,chutes, means for moving the same to properly place the same in-posltionto carry away the materials raised by the elevator, and means fixed 1nthe tower for receiving the turntable and conveyor, when not in use, andthen directly supporting the same, the said means being so arranged thatthe turntable and conveyor may run directly thereon from the boom.

In testimony whereof I have signed my name to this specification in thepresence of two. subscribing witnesses.
